CEA designed and built a superconducting joint test facility called SELFIE. The test performed on SELFIE aims to measure the superconducting joints sample resistance (few nΩ) in cryogenic condition (liquid helium bath at 4.2 K) at 70kA in self-field. This system is designed to perform easily and in a more efficient way. This facility has already been declared ready for operation in January 2022. Furthermore, the SELFIE facility is also available for other superconductivity materials.
